In the first period the maximum fall occurs with south- 

 west, and in the second period with south winds ; and the 

 greatest differences between the two periods are with winds 

 from south-east, south, south-west, and west, the differ- 

 ences with south-east and south winds being negative, and 

 those with south-west and west winds positive. Comparing, 

 then, the sums of the amounts which fell under the first 

 two winds with those which fell under the last two, we 

 have the following results : ; —

It will be observed that in every year of the first period 

 (1858-62) the differences were negative, while in every 

 year of the second period (1863-68) they were positive — 

 or, that the amounts of rainfall under south-west and 

 west winds were invariably greater than those under 

 south-east and south winds during the years when the 

 number of solar spots was above the average, and inva- 

 riably less in the years when the number of sun-spots 

 was below the average, — and, further, that the greatest 

 difference in the first series of years occurred in i860, 

 at the time of a solar- spot maximum, and that in the 

 second series in 1866, at or very near the time of a solar- 

 spot minimum. 



Considering the irregular character of rainfall, both in 

 the times of its occurrence and the amounts in which it
